The mythology have change greatly since Jewish era and Christian era. The original story before Christianity, Adam and Eve were originally from a story of ancient Africa pegan faith.
In the original story, there many gods in heaven. Amount the many gods, there was one name Yahwha (AKA Christ), Yahwha has a son (later Judiasm name him Adam) Adam married a beautiful goddess name, who is a strong and independent woman. (Later Hebraw name her Lilith) But Adam is what we today refer to as a rich spoil brat and demand for Lilith to serve him, unwillingly, Lilith left and came down to earth, using mud, she created many human (thus in original story, man are not created by Christ, but by Lilith) because she is lonely, Angry Yahwha threaten to send floods and demons to kill Lilith's children if she don't return. Lilith said no, So, Yahwha send a giant flood to flood the earth and send demons. Lilith kill the demon and seal the portal in heaven that allow flood water to come, but by that stage, many of Lilith's children died. Lilith created a powerful dragon name Satan to protect her children and return to heaven, for her revenge, Because Lilith refuse to return, yahwha took a rib from Adam and create a woman to be his wife (Jews later name her Eve), Eve is innocent, Lilith transform into a giant snake and manipulate Eve to eat a golden fruit and let Eve to let Adam to also eat it, after eating it, the fruit turn Adam and Eve mortal and they was been casted down to earth by the other gods. Lilith then use her lust, to seduce Adam and suck try his life source, she then cursed Eve and cause her to have an abortion. An angry Yahwha see revenge on Lilith by punishing her children, so, the battle between Yahwha and his angels, led by Michael and Lilith and her dragons, led by Satan, continue.
In early story, Lilith and Satan was the good guy, Yahwha and Michael was the bad guy, but by Jewish era, it was reverse, because Jew believe they are children of Adam and Eve, not the creation of Lilith. Later, Lilith got wrote off, all together.
